Makes the car mor fun to drive. I'm thinking about buying it for my 330i next year.But it has some disadvantages in the connection to the DTC/DSC electronical units when they are normally switched on: The DTC/DSC interference is much faster/heavier than normal. So you have to drive always with those systems turned of or get used to power-loss when flooring it...

Thatīs exactly why LSD conversions are offered so seldom. It does mess up DSC / DTC big time, unless the DSC/DTC is adapted. Which it is on the M-cars but which hardly any aftermarket company can muster.

Just imagine the liability issues....

While switching off DSC/DTC for serious performance driving is fine, on a non-dedicated track car for daily use, I would allways want a fully operational (switchable for moments of fun) DSC. You cannot allways foresee whatīs coming up and in certain situations DSC really can be a life saver.
